This patch adds the machine dependent call for pcibios_bus_add_device, since the previous patch separated the calls out between the PowerNV and PowerVM. The difference here is that for the PowerVM environment we do not want match_driver set because in this environment we do not want the VF device drivers to load immediately, due to firmware loading the device node when VF device is assigned to the logical partition. This patch will depend on the patch linked below, which is under review. https://patchwork.kernel.org/patch/9882915/ Signed-off-by: Bryant G. Ly <redacted> Signed-off-by: Juan J.
